Thisinvention relates to a locking device for motor vehicle wheels.

The object of the invention is the production of a locking device for motor vehicle wheels,

wherewitha-wheel can be easily locked to, and disengaged from a vehicle.

The second object of the inventionis the production of a locking device for motor vehicle wheels which will remain lockedduring the rota- .1-tions of the wheel.

Referring to Figs. 1 to '7 of the drawings, an automobile wheel is indicated in its entirety by the numeral 20, having the hub 2|, the felly 22, and the shoe 23 for the pneumatic tube. The radially outer portion of the hub 2| has integral therewith the cylindrical flange 28. Wire spokes -129 extend between the hub 2I and the felly 22 of the wheel.

The hub 2| comprises the cylindrical shell 32, which joins with the flat-clamping and locking wall 33. A plurality of circular openings34 are indicated in the wall 33, and the latter join with the curved openings 35. The walls of the openings 35, at their ends are connected by the curved end portions 36. Stop lugs 31 extend from the wall 33, adjacent to certain of the openings 34. The walls of the openings 35 are concentric with the axial center of the wall 33 and a circle struck through the middle portions of the openings 35, extends through the middle portions of the openings 34. The shell 32 joins with the converging "wall 38, having the opening 39. A cylindrical sleeve 40 extends from the wall 33.

The brake housing of the wheel is indicated in its entirety by the numeral 42, and comprises the cylindrical shell 43, the head 44, with the flange 45, having the central opening 46.

An inner hub is indicated in its entirety by the numeral 50, and comprises the barrel 5|, which at its inner end has integral therewith the radial flange 52; An outer annular disc 53, and an inner annular disc 54 extend from the inner face of the barrel 5|.

A plurality of studs are each indicated with the threaded portion 55, the shank 56, smaller in diameter than the portion 55, and the outer threaded stem 51, smaller in diameter than the shank 56. The threaded portions 55 of the studs extend through the flange 52, and the flange 45, of the head 44. Nuts 58 clamp the said studs in place.

Ball bearing races 63, for the ball bearings 64, bear on the disc 53, and ball bearing races 66, for the ball bearings 67 bear on the disc 54.

The axle for the wheel is indicated at 68, and has integral therewith the threaded shank 69. A clamping nut 10 is provided for the shank 69. 5

A grease pot 12 is indicated, having the cylindrical wall 13, the head 13 with the octagonal pocket 14, and the outer flange 75. The inner end of the grease pot extends into the barrel 5| and the flange I5 bears on the outer end of said barrel. Screws 11 in threaded engagement with the barrel 5| keep the grease pct 12 in place.

A cap indicated in its entirety by the numeral I8 is rotatably supported on the sleeve 40. The said cap 78 comprises the cylindrical shell 79, hav- 25 ing the head 80, with the cylindrical projecting portion' 8|. The inner end of the shell 19 has integral therewith the spur gear 82. From the portion 8| extends the cylindrical barrel 83, having the longitudinal rectangular opening 84 and four 30 locking openings 86, extend through the wall of the barrel 83.

A plurality of locking pinions 89 are each indicated having the clamping barrel 90, from which extend the teeth 9| which are in mesh with the 35 teeth of the spur gear 82. The said locking pin ions are in threaded engagement with the threaded stems 51 of the studs.

A detachable hood-shaped cap is designated in its entirety by the numeral I99. At the lower edge of said cap is indicated the return bend annular portion IllI having the curved end I02. At the top of the said hood I is indicated the depressed annular flange IUS. The cap I0!) is snapped in place by detachably locking the curved end I02, with the edge of the cylindrical opening 39, of the hub 2|.

Upon the head 86 of the cap I8 is positioned the annular bearing ring I88, which has integral therewith the radially extending arms I 89, the outer ends of which bear against the inner face of the wall 38 of the hub 2|, and are detachably fastened thereto by the screws H9. The bearing ring I98 maintains the cap 78 in operative posi tion. A supplemental lock is designated in its entirety by the numeral H4, and is shown with the barrel I I5, square in cross section, and from the latter extends the octagonal plug II6, which is adapted to be seated in the pocket 14. The bolts of the lock are indicated at II1. A flange I26 extends from the barrel I I5, which is adapted to be seated upon the flange I06. The key for the lock is indicated in dotted lines at I22.

Referring to Figs. 8 and 9 a modification is indicated in which no supplemental look like M4 is required. In this instance the hub of the wheel is indicated at MI, with its sleeve I42, similar to 40. A detachable cap for the hub is shown at I45. A cap I48 .rotatably bears on the sleeve I42, and has integral therewith at its axially inner end the spur gear I49, similar to 82. The cap I48 is indicated with the stepped head I50 from which extends the sleeve I52, having the square opening I53. A bearing ring I bears upon the head I56 and has extending therefrom the arms I56, which latter are detachably connected to the hub MI by the screws I58. A supplemental locking cover I62 is indicated having the square pocket I63 and the octagonal pocket I64. An annular flange I having the plurality of curved openingsor arcuate slots I66 is integral with the cover I62. A pot I10 is indicated with the flange HI and the head I12 having the octagonal pocket I13. An inner hub is indicated at I26, and supports the pot I16. The screws I14 maintain the pot I10 in place. From the bearing ring I55 extend the studs I15, which pass through the curved openings I66. Wing nuts I11 are provided for the studs I15 to lock the cover I62 in place. By means of the cover I62, the cap I48 is locked against rotation relative to the demountable wheel when the wing nuts I11 are screwed down hard against the annular flange I65. When the nuts I11 are rotated so as to back them slightly, the cap I48 may then be rotated relative to the demountable wheel within the limits of the arcuate slots I66.

Referring to Figs. 1 to 7, to secure the wheel 26 in place, the sleeve 46 is mounted on the barrel M in position so that the circular openings 34 register with the pinions 89 and the wall 33 is brought to bear against the flange 45. The wheel is then turned in the direction of the arrow A, Fig. 3, until the curved end portions 36 of the curved openings 35 bear against the shanks 56 of the studs. A wrench is then inserted into the rectangular opening 84, and said wrench is turned whereby the cap 18, with its spur gear 82 is turned. The said spur gear82 will turn the pinions 89, which latter will move down the threaded stems 51, until they are simultaneously clamped to the clamping and locking wall 33. The wrench is now removed and the square barrel H5 of the supplemental lock H4, is inserted into the rectangular opening 84 and the octagonal plug H6 is inserted into the octagonal pocket 14 of the grease pot. The key I22 of the lock is turned to enter the bolts I I1 into a pair of the locking openings 86.

To detach the wheel 20 from the brake housing 42, the key I22 is turned to unlock the bolts II1 from the locking openings 86, and the lock H4 is removed. The wrench is now inserted into the rectangular opening 84 and turned to disengage the pinions 83 from the clamping .and locking wall 33. The wheel 20 is now turned in a direction opposite the arrow A, until the stop plugs 31 bear against the said pinions 89 and thereby the circular openings 34 are brought into register with said pinions 89, and the wheel can be removed from the brake housing 42.

With the modification indicated in Figs. 8 and 9 to position the wheel 20 in place, the detachable cap I45 is removed from the hub MI and the locking cover I62 is removed from the sleeve I52. Next a wrench is inserted in the square opening I53 and turned, as already described, which clamps the pinions 89 against the clamping and locking plate 33, not shown. Next the locking cover I62 is fastened in place and the cap I45 is sprung in place.

To detach the wheel indicated in Figs. 8 and 9 the operator first removes the cap I45 from the hub MI and then removes the cover I62 from the sleeve I52. The operator then inserts a wrench in the square opening I53, turns the wrench to unlock the pinions 89 from the wall 33, and proceeds as already described.

Various modifications may be made in the invention and the present exemplifications are to be taken as illustrative and not limitative thereof. V
